whose引導定語從句可以指物嗎

請看下面這道題：

I saw some trees __________ leaves were black with disease.

A. its                        B. whose                        C. his                                       D. the

分析：此題應選B。容易誤選A。許多考生認為，關系代詞whose和who，whom一樣，只能指人，不能指物。

事實上，用作關系代詞的 whose 與 who，whom不一樣，它不僅可以指人也可以指物(用作定語)：

There are some students whose questions I can’t answer. 有些學生的問題我不能回答。

Can you see the mountain whose top is covered with snow? 你看得見山頂上覆蓋著雪的那座山嗎?

Here is a word whose meaning escapes me. 這里有一個詞，我一下想不起它是什么意思了。

當先行詞為物時，其后引導定語從句的 whose＋n. 也可換成 the＋n. ＋of which / of which＋the＋n.：

■窗戶破了的那座房子是空的。

正：The house whose windows are broken is empty.

正：The house the windows of which are broken is empty.

正：The house of which the windows are broken is empty.

但是如果 whose所修飾的名詞中心詞之前有數詞或其他限定詞，則不用 whose，而用of which：

There I saw a large table，two legs of which were broken. 在那里我看見有一張大桌子，其中有兩條腿斷了。
